Overvue is a lightweight status and short term planning system using the HALP methodology to quickly point out 'at risk' tasks and goals.
HALP is an acronym that stands for 'Help Avoid Lost Productivity'. Halp uses color-coded status that let you know if there is no risk(green), help needed soon(yellow), help needed immediately(red) and not applicable(blue).
